Application led April 2, 1917. Serial No. 159,360.

To all whom t may concern.'

Be it known that I, FRANK M. Dnvn- REAUX, a citizen of the UnitedStates, and resident of Syracuse, in the county of Onondaga and State ofNew York, have invented new and useful Improvements in Padlocks, ofwhich the following is a specification.

This invention relates topadlocks and has particular reference to theclass of padlocks in which a sliding key rather than a rotary key isemployed as an unlocking means.

The primary object of the invention is to provide, in a padlock, alocking means of such a character as will not permit the use of anyinstrument, other than one which has been designed in accordance withthe interior mechanism of the padlock, to facilitate the unlocking ofthelocking means.

Another object of the invention is to provide, in a padlock, a meanswhereby the shackle of the padlock, after having been unlocked, will becaused to assume an open position with respect to the padlock proper,and to retain such a position until it has become desirous to replacethe shackle again into a closed position. y

With the above and other objects in view, the invention will be morefully described in the following description, taken in conjunction withthe accompanying drawings, and the particular features of novelty willbe pointed out in the appended claims.

In the drawings, in which similar characters of reference denote similarparts in the views,

Figure 1 is a face view of the lock with its cap removed, showing thelocking elements in a locked position,

Fig. 2 is a cross section of Fig. 1, taken on the line :I0-, showing itfrom the. end which receives a key,

Fig. 3 is a face view of a key,

Fig. 4 is a top plan view of the tumbler disks and the tumbler segments,taken on the line -m of Fig. 1 and showing a portion of the case insection,

Fig. 5 is a face view of a tumbler segment, and

Fig. 6 is a face view of a tumbler disk.

Now referring more particularly to the drawings, A indicates a case'comprising a wall 10, a flange 11, and a cap 12. The flange 11 isformed integral with the wall 10 at its outermost edge and is adapted toreceive upon its face 13 the cap 12 which serves as a closure for thecasel A.

A shackle 14 is pivoted within the case A at a point relatively near theinner wall 15 of the flange 13, and is provided at its pivoted end withan elongated member 16 which carries a lug 17.. The shackle 14 isprovided at its movable end with a notchv 17 which is adapted to receivea hook 18, carried by an end 19 of a pivoted lever v20. The hook 1 8carried by the end 19 of the lever 20, is held normally within the notch17, as is shown in Fig. 1, by means of a flat spring 21, having one endsecured to the hub 22 of the lever 2O and its other end engaging a pin23 which passes through the wall 10 and the cap 12 of the case A.

An elongated rib 24 is disposed, within the case A, upon the wall 10 andis provided j :and the cap 12'of the case A on which vis revolublymounted a plurality of 'tumbler disks 33. The tumbler disks 33 are eachprovided with a stop 34 and a plurality of teeth 35. A plurality oftumbler segments 36y are disposed between 'the tumbler disks 33 and arefastened therebetween by means of pins 37 passed through each of thetumbler disks 33 and each of the tumbler segments 36. The tumblersegments are each provided with a lug 38 and a stop 39. In order to holdthe tumbler segments 38 and the ltumbler disks 33 in a normal position,as is shown in Fig. 1, there is provided a spring 40 which is coiledaround the pin 32, having one end 41 adapted to slidably engage one endof the tumbler segments 38 and the other end 43 adapted to engage a stoppin 44 projecting through 'the wall 10 into the case A.

When it is desired to unlock the locking elements within the case A, thekey 27 is inserted into the key way 45, whereupon the end 46 of the key27 comes into contact with the stops 34 of the tumbler disks 33 and thestops 39 of the tumbler segments 36. Upon moving the key farther intothe key way 45, the teeth adjacent to the stops 34 of the tumbler disks33 move into the notches 47 of the key 27. When the key 27 has completedits inward course, thelugs 38 of the tumbler segments 36 will haveentered successively the apertures 4S, 49 and 50 and the teeth 35, whichare the farthest distance from the stops 34, of the tumbler disks 33will be positioned in the notches 51 of the key 27. l/Vhen the tumblerdisks 33, together with the 'tumbler segments 36 have been rotated asabove described, the tumbler segments 36 will have come into contactwith the end 52 of the pivoted lever 2O and will have moved itsufficiently about its axis 53 to permit the hook 18 of the lever 2O tobecome disengaged from .within the notch 17. Upon the releasing of thehook from the notch 17 the shackle 14 will assume an open position withrespect to the lock proper due to the influence of the spring 30 actingupon the elongated member 16. Upon relieving the pressure from the key27, necessary to hold it within the case A, the tumbler disks 33,together with the tumbler segments 36, revolve about the vpin 32 untilthe teeth 35 of the tumbler disks 33 which are farthest distance fromthe stops 34: of the tumbler disks 33, come into contact with the stoppin 44, and the pivoted lever 20 acting under the influence of thespring 21, will assume a position such as will permit the hook 18 tosnap into a locked 'position when the shackle lt has been moved to theposition as shown in Fig. 1.

I claim:

1. A padlock comprising a case, a shackle having one end pivoted withinthe said case, a pivoted lever carried between the walls of the case,and provided at one end with a hook adapted to'engage within a notchcarsaid pin having one end adapted to engage -1 an end of the saidtumbler segments and the other other end engaging a stop pin passedthrough the wall of the said case.

3. The combination with a padlock, comprising a case, a shackle, apivoted lever carried between the wall and the cap of the case, tumblerdisks rotatably mounted on a pin passed through the wall and the cap ofthe case, teeth carried on the periphery of each of the said tumblerdisks, a stop carried by each of the said tumbler disks, a plurality oftumbler segments disposed between the said tumbler disks, and lugcarried by each of the said tumbler segments, of a key provided withnotches adapted to receive the teeth of the said tumbler disks and withapertures adapted to receive the lugs carried by the said tumblersegments.
